Ball grinding mill grinding-balls is the important grinding medium of ball grinding mill, which is the steel ball in the ball grinding mill shell. All the materials which are ground by the ball grinding mill are finished by the collision and friction between the steel balls. Therefore, the quality of ball grinding mill grinding-balls and the quality of the material also appears to be particularly important.

High-carbon high-alloy casting ball grinding mill grinding-balls and high-carbon low-alloy forging or casting ball grinding mill grinding-balls are widely used by Chinese ball grinding mill manufacturers. While in dry production of thermal power plants and cement industry, the vast majority of Chinese ball grinding mill manufacturers is using high and low chromium casting iron ball grinding mill grinding-balls. In the wet process of mining machinery, ball grinding mill is the application of high-carbon low alloy ball grinding mill grinding-balls.

According to official data, the types of Chinese ball grinding mill grinding-balls is large, due to imperfect market economy, the use of ball grinding mill is not based on the process technique benefits, on the contrary, a lot of Chinese ball grinding mill manufacturers use cement ball grinding mill for grinding cement, the optional arbitrary of the ball grinding mill grinding-balls is very large. The high-alloy cast iron ball grinding mill grinding-balls has excellent anti-wear properties that the higher the alloy, the better the anti-wear properties, and has good economic benefits. Some people have misunderstood, the applications of high chrome ball cement ball grinding mill is good, but the power plant is not suited, in fact, it has a large number of good record that thermal power plants using high chrome grinding ball both at home and abroad.

Under the premise of the material selected, it is also very important that the matching of ball grinding mill grinding-balls. The ideal ball grinding mill grinding-balls gradation combined with the ideal liner surface shape maximizes the efficiency of the ball grinding mill. The correct choice of material is the guarantee that the ideal ball grinding mill grinding-balls gradation, and ideal long-term shape of the liner surface to maintain, but also allows the ball grinding mill to maintain the best condition.
